Patented Sept. 9, 1919.

Application filed Nogemhcr 2a, .1917. Serial No. 204,466.

To all whom it may concern:

Be it known that I, Gnouon Nonanm AL nnnn, citizen of the United States of America, and resident of Swampscott, in the county of Essex and State of Massachusetts, have invented. new and useful Improvenients in Fittings for Airplanes and the like, of which the following is a specification.

This invention relates to fittings for framework and more particularly to fittings for connecting the frame members of airplanes and the like having. two or more members meeting at a common point and having wires or other bracing members radiating from the common point. a a y a The principal objects of the invention are to provide fittings which possess both strength and lightness, which are simple to construct and easy to apply, which have means for simply and rigidly locking the parts in position, which have means for pivotally attaching frame members thereto, which are readily adaptable to different positions and conditions of usage, and which possess other novel features of utility which will be apparent from the following description andthe accompanying drawings, in which-- y Figure 1 is an elevational view of the preferred embodiment of the present invention, my improved fitting being illustrated as applied to the fuselage of an air- 7 plane;

Fig. 2 a side GlBVtLiZlOlI ofthe fitting, viewed from the right of Fig. 1;

Fig. 3 is a perspective view of the fitting;

and y y a Figs. 4:, 5, 6 and 7 are perspective views of the four component parts of the fitting. The present invention is illustrated in my copending application filed on even date herewith and. as in the copending application the fitting is applied to an air plane fuselage. The framework of airplanes usually involves four or more longitudinals connected together by means of struts and guy wires, as illustrated in said copending application, and in the attached drawings I have shown a longitudinal 1, vertical and horizontal struts 2 and 3, and guy wires 4, 4 5 and 6. I have also illustrated a main airplane wing at 7 and a king post at 8, the king post extending upwardly from the longitudinal to meet a similar post extending upwardly from the other side of thefuselage, theltwo posts being intended to support the main wings by means of guys or stays (not shown). In the particular structure illustrated the horizontal strut is recessed to receive the longitudinal 1 so that the lower portion of the end of the horizontal strut is disposed betweenthc longitudinal and the verticalstrut 2, but it will be understood that the longitudinal may be of the same than the horizontal strut.

My improved fitting, as adapted to apply to the above described environments, comprises the four parts A, B, O and D, illustratcd respectively in Figs. 4, 5, 6 and 7 The part A comprises a strap bent to fit around the longitudinal 1 and having its end 9 bent to extend along the upper side or greater depth of the horizontal strut 3. In the preferred embodiment of the invention the strap A is so bent that the inner end 10 is overlapped by the side portion 11 of the strap although the overlapping of these portions is not es .sential to a successful fitting. In order to attach. guys or stays to the fitting the strap A is provided with lips 12 and 13 extending obliquely from the sides thereof and these lips as well as certain other lips hereinafter a.

described may if desired be reinforced by plates 14. The lips are provided with openings 15 for the purpose of attaching them to the guys. At the top of the part A are provided lips 32 for attaching the king posts 8 to the fuselage as illustrated in Figs.

1 and 2.

Thepart B comprises a strap bent overthe longitudinal 1 and having ends 16 and 17 extending along the horizontal and vertical struts 2 and 3. Vhen the struts 2 and 3 extend from the longitudinal at an angle of with respect to each other as illustrated, the bend 18 in the part Bis arightangle bend, but in any event the bend is preferably made to conform to the surface outlines of the longitudinal and abutting struts. Lips 19 extend outwardly from the end 17 and lips 20 extend upwardly. from the end 16 of the part B for purposes here- The lower end tion 25, a vertical portion 26 and an oblique assembled the end 16 of part B surmounts the end 9 of part A and the lips 32 and 20 on these parts lie in juxtaposition with the openings therein in alinement so that a bolt 28 maybe passed through the openings in the lips and through the lower end of the king post 8. In a similar manner the lips 19 and 23 on parts B and C also he in j ustaposition with their openings in alinement so that the form a rigid support for the main wing 7 or other part which it may be desired to at tach to the fitting. The part D1 fits beneath the part C with the ends 24. and 27 juxtaposed in parallel contact with each other. 17 of part 13 extends along the outside of the vertical strut 2 and de pending 'end 26 of part I) extends along the inside of the vertical strut 2 so that a bolt 29 may be passed through the openings in the ends 17 and :26 and through the strut 2. The lips 11 and 13 on part A are bent at an oblique angle to the sides of the part A so that they will be disposed in alinement with the guys a and 5 connected thereto.

As above stated, the parts A, B, O and D are preferably secured together, as by spot welding, so as to alford a unitary device; and it obviously follows that mstead of forming the parts separately and attaching them together they may be formed integrally. On the other hand, the parts are so related to each other that they are bound together when secured in position even though they are not welded or other wise secured together, and I therefore desire to protect my improved fitting when the parts are either attached to or detached from each other.
